Top Gear 2

Top Gear 2 (known as Top Racer 2 in Japan) is the sequel to the 1992 game Top Gear, first released in September, 1993 for the Super NES, May 24, 1994 for the Sega Genesis and in 1994 for Amiga. It was developed by Gremlin Interactive and published by Kemco for the Super NES and by Vic Tokai for the Genesis.

Gameplay

In this sequel, the game becomes more realistic, with a damage diagram on the left side of the screen, slower cars, and the possibility to upgrade your machine. The cars become more difficult to handle and the opponents are faster and tougher than in the previous game. The new addition of weather also plays a role, forcing the player to change from dry to wet tires.

The game takes place in 16 countries including 64 cities, starting with Australasia (Australia and New Zealand). After each country is beaten, the player is given a password, which can be later used to pick the game back up from that position. Because of agreement to naming rights, the Giza Necropolis in Egypt was renamed to Hugh Sitton, a photographer of Corbis Corporation.

Samsung Gear 2

The Samsung Gear 2 and Gear 2 Neo are smartwatches produced by Samsung Electronics. Unveiled on February 22, 2014 at Mobile World Congress, the Gear 2 line is a successor to the Samsung Galaxy Gear.

In comparison to the Galaxy Gear, the most significant change made to the Gear 2 line was the replacement of Android with the Samsung-developed Tizen operating system, promising improved functionality (such as Samsung's S Health software and an integrated music player) and battery life. The design of the device itself was also refreshed with the move of its camera from the watchband to the watch itself (allowing users to replace their own bands), along with the addition of an infrared blaster and optical heart rate sensor.

Specifications

Hardware

The Gear 2 retains a similar hardware design to the original Galaxy Gear, although a Home button has been added below the screen, and the device's 2-megapixel camera was moved from the strap to the top of the watch itself, alongside a newly added infrared blaster. This particular design change allows the strap to be user-replaceable. Two models of the Gear 2 were released, the Gear 2 and Gear 2 Neo; the Gear 2 has a steel exterior and includes a camera, while the Gear 2 Neo is made from plastic and excludes the camera. They are otherwise identical.

Gear

A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear. Two or more gears working in a sequence (train) are called a gear train or, in many cases, a transmission; such gear arrangements can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine. Geared devices can change the speed, torque, and direction of a power source. The most common situation is for a gear to mesh with another gear; however, a gear can also mesh with a linear toothed part, called a rack, thereby producing translation instead of rotation.

The gears in a transmission are analogous to the wheels in a crossed belt pulley system. An advantage of gears is that the teeth of a gear prevent slippage.

When two gears mesh, and one gear is bigger than the other (even though the size of the teeth must match), a mechanical advantage is produced, with the rotational speeds and the torques of the two gears differing in an inverse relationship.

Sega Genesis

The Sega Genesis, known as the Mega Drive (Japanese: メガドライブ, Hepburn: Mega Doraibu) in most regions outside North America, is a 16-bit home video game console which was developed and sold by Sega Enterprises, Ltd. The Genesis was Sega's third console and the successor to the Master System. Sega first released the console as the Mega Drive in Japan in 1988, followed by a North American debut under the Genesis moniker in 1989. In 1990, the console was distributed as the Mega Drive by Virgin Mastertronic in Europe, by Ozisoft in Australasia, and by Tec Toy in Brazil. In South Korea, the systems were distributed by Samsung and were known as the Super Gam*Boy (Hangul: 수퍼겜보이), and later the Super Aladdin Boy (Hangul: 수퍼알라딘보이).

Designed by an R&D team supervised by Hideki Sato and Masami Ishikawa, the Genesis hardware was adapted from Sega's System 16 arcade board, centered on a Motorola 68000 processor as a primary CPU and a Zilog Z80 as a secondary processor. The system supports a library of more than 900 games created both by Sega and a wide array of third-party publishers and delivered on ROM-based cartridges. It can also play Master System games when the separately sold Power Base Converter is installed. The Genesis has benefited from several peripherals and network services, as well as multiple first-party and third-party variations of the console that focus on extending its functionality.
